[Default]
2 -0.999 to 1.000 The values that are to be monitored for each threshold limit are defined here.
2329 [+ 0.900]
2335: [+ 0.700]
Notes
If the power factor becomes more lagging (i.e. inductive, Fig. 78) than a lag‐
ging PF value (positive) or a leading PF value (negative) for at least the delay
time (parameters
action specified by the alarm class is initiated.
2 0.02 to 99.99 s If the monitored generator power factor is more lagging than the configured
limit for the delay time configured here, an alarm will be issued.
2330: [30.00 s]
2336: [1.00 s]
Notes
If the monitored generator power factor returns within the limit before the
delay expires the time will be reset.
2 Class A/B/C/D/ Each limit may be assigned an independent alarm class that specifies what
E/F action should be taken when the limit is surpassed.
2326: [B]
2332: [E]

2 Yes The control unit automatically clears the alarm if the fault condition is no
longer detected.
[No] The control unit does not automatically reset the alarm when the fault condi‐
tion is no longer detected.
The alarm must be acknowledged and reset by manually pressing the appro‐
priate buttons or by activating the LogicsManager output "External acknowl‐
edgement" (via a discrete input or via an interface).
2 [Yes] Monitoring for fault conditions is not performed until engine delayed moni‐
toring is enabled. The engine monitoring delay time (param‐
eter
parameters assigned this delay.
No Monitoring for this fault condition is continuously enabled regardless of engine
speed.
The power factor is monitored for becoming more leading (i.e.
capacitive) than an adjustable limit. This limit may be a leading or
lagging power factor limit. There are two leading power factor
alarm levels available in the control. This monitoring function may
be used for monitoring an underexcitation with a warning and a
shutdown alarm level. Both alarms are definite time alarms.

on page 372 for a detailed description of this monitoring function.
